Apollo.io and ZoomInfo are the two names that come up when a team decides to buy a B2B contact database. They solve the same core problem — find companies and the people inside them, with emails and phone numbers — but they sit at opposite ends of the market on price, contract, and who they're built for.
The short version
Apollo.io is the self-serve, product-led option: a large contact database with built-in email sequencing, a free tier, and month-to-month plans that a single rep or a small team can start on today.
ZoomInfo is the enterprise standard: deeper firmographic and intent data, stronger phone coverage in some segments, and the compliance and integrations big sales orgs need — sold through annual contracts and a sales process, at a price to match.
If budget and self-serve access matter most, Apollo wins on accessibility. If data depth and enterprise features justify the spend, ZoomInfo is the heavier tool.
Data and coverage
Both maintain very large contact databases. ZoomInfo has historically been regarded as the gold standard for depth — firmographics, org charts, intent signals, and phone data — particularly for mid-market and enterprise accounts. Apollo's database is also large and has closed much of the gap, and its data is more than good enough for most SMB and mid-market prospecting. As with any database, accuracy varies by region and seniority, and every email you get is only as good as the last time it was verified — so expect to validate before you send at volume, whichever you choose.
Pricing
This is the starkest difference.
Apollo.io has a free plan and paid tiers that, as of 2026, run roughly $59–$149 per user per month (billed annually), with credits governing how much data you can pull. You can sign up and pay by card.
ZoomInfo doesn't publish per-seat pricing. It's sold as an annual contract, typically starting in the low five figures and climbing well beyond that with add-ons for intent, data, and seats — real all-in costs commonly land in the tens of thousands per year. Expect a sales call, not a checkout page.
Always check each vendor's current pricing directly — both change plans and credit models frequently.
Who each is for
- Choose Apollo if you're a founder, a small team, or a mid-market sales org that wants to start now, self-serve, and keep costs predictable — and you value the built-in sequencing.
- Choose ZoomInfo if you're an enterprise team that needs the deepest data, intent signals, and integrations, and has the budget and procurement process to support an annual contract.
What both leave you to do
Here's the thing neither Apollo nor ZoomInfo solves: a database gives you contacts, not conversations. You still have to turn a list of names and emails into messages people actually reply to — and on LinkedIn, where much B2B relationship-building happens, a bought email list is often the wrong starting point. Cold emails from a purchased database are easy to ignore; a personal LinkedIn message referencing something real about the person is not.
The LinkedIn-native alternative
Conextly comes at prospecting from the other direction. Instead of selling you a database to email, it works from LinkedIn itself — the richest, most current source of who people are and what they do:
- Find the right people with LinkedIn's own search and Boolean filters — no separate data subscription, no stale emails. See Find.
- Track them on a live pipeline and get flagged when someone changes jobs — the strongest moment to reach out. See Track.
- Draft & Approve a personal first message for each person, written from their actual profile, that you approve before it sends. See Draft & Approve.
Apollo and ZoomInfo answer "who can I contact?" Conextly answers "how do I turn these people into conversations without spamming them or risking my account?" Many teams use a data tool for coverage and Conextly for the LinkedIn outreach that actually gets replies.
